I joined the this forum on the day I first installed Manjaro and, even though several years have passed since then, I still consider myself to be much of a novice and I still learn something new almost every day from perusing the Latest Topics page.
Manjaro is a rolling release that requires regular maintenance/updating, and one of the first things I learned was to always read Latest Announcements topics - Manjaro Linux Forum or Latest Announcements/Stable Updates topics - Manjaro Linux Forum before doing any updates, as sometimes important procedures have to be manually done before or immediately after updating. It can also be useful to let the update notification sit in your system tray for a few hours so that you can first have a read of the applicable update forum thread to see if other users have encountered any issues and if any solutions are offered. Please see edit at bottom of this post for correct ARM links
BTW, the updates forum does have RSS feeds that can be added to any feed reader. The one I would recommend for you is: Stable Updates - Manjaro Linux Forum
If you want to keep an eye on what is happening regarding updates in all branches (Unstable & Testing especially), then this is the RSS feed: Announcements - Manjaro Linux Forum
If you want an operating system that is “not too complicated if possible”, then I would strongly recommend that you read the following topic to help you decide if Manjaro is the right choice for you:
I’m not saying that you shouldn’t stick with Manjaro, but people who don’t have a lot of spare time available to maintain their system should really consider whether a fixed-point release distro might be a better option for them.
